Application mea muy s,

rlhis invention relates to terrules torthe connection ot a closet withDurham or threaded pipe work usually utilized in plumbing installationstor residences. y,

T he purpose et this invention is to provide a terrule that may be cutto length upon the completion or" a building, and that provides a readymeans for testing the worlrv subsequent to installation and is ol' acharacter to prevent filling ot the piping with waste ma terial such asplaster, shavings etc., thatheretofore in open worl tends. to clog thepiping.

ln plumbing installations the Durham type ot fittings are ot a standardsize and, inasmuch as the floor levels and tne dist-ance between thefitting and terminal portion ot the piping varies due to the usualinaccuracies in the i'loor levels and distance between tioors, itis adiiticult matter to properly fit the parts. An object ot my invention isto provide iitting that is universally adaptable for the connection ot acloset cr like litting with the piping and that remains in place untilthe building has been completely linished and r then may be cut to thedesired length. ltis also an object ot the invention to provide aninexpensive cast iron structure for this purpose that is or" suiiicientstrength to withstand the strain incident to erection, thatmay bereadily and cheaply attached and avoids necessity ot an accurate littingof the parts.

These and other objects and the several novel features ot the inventionare hereinalter more i'ully desibed and claimed, and the preferred formot construction ot a terrule embodying my invention is shown in theaccompanying drawings in which- Fig. 1 is an elevation partly in sectionshowing my improved l'errule or closet connection in its relation withthe base ot a closet fitting.

Fig. 2 is a section taken on line 2-2 ot' Fig. l. i

In the drawing l indicates the usual base member ot a closet fitting towhich my ferrule is to be attached connecting the same with the pipingwhich is indicated at 2. The ferrule is usually caulked to the member land is provided with a threaded lower end 'for connection with the pipe2 and adjacent the lower end the wall ot the terrule is made thicker asindicated at 3 to secure strength. Exteriorly of the walls at thisstrengthened point is provided a portion 4c ot greater diameter andnotched as indicated at 5 tor the use et a Spanner wrench thereon. Above1996. Serial No. 126,367.

this portion l the wall oit the t'errule is provided with a series otcircumferential grooves 6 spaced a shortdistance apart which pro-k videweakened portions in the ywalls and, be-

ing made 'of cast iron, enables the terrule to i be severed at any etthe desired groovesthrough the use ot a chisel.l rlhus, subsequent to aninstallation the part ot the 'lerrulewhich projects upwardly through theportion l with which it is connected may be cut oli?. The terrule isoriginally made with a closed end portion Z which has av centralapertured end threaded boss 8 with which a plug may be utilized to sealthe same as indicated by dotted lines 9. The purpose ot the closed endmember and threaded boss 8 is to provide a convenient connection tor atesting apparatus by means of which it may be determined as to whether`or not the installed system would permit ot leakage.

Thisis usually accompllshed by attaching a pipe to this threaded.V

opening 8 and subjecting the piping system to water pressure. Subsequentto this testing the plug 9 1s inserted and the plumbing system remainsin this closed condition until the actual completion ot building andthus the terrule and the piping are sealed in aV f manner to preventwaste material such as plaster, shavings etc., being introduced into thepiping. On completion oi the building and by use of an ordinaryl chiseland hammer the upper end to the extent to which it projects through thefitting may be removed and the closet fixture mounted in proper relationtherewith, it being usually attached by bolts 10 to the member l.

By' the arrangement ot circumferential grooves 6 and thereby providingfor the' ready removal of the projecting end portion of the terrule,this ferrule is adapted toy be used universally with this type otthreaded pipe work without necessity ot utilizing a part that is ot aspecific standard 'length which through variation in buildingconstruction is oftentimes too short or too long. The reinforced portionnear the lower end provides a 'ferrule ot a construction that willnotcrush or detorm under the strain of a wrench by means ot which it isattached to the piping.v

This device also enables the parts Vot thev plumbing system to beerected without necessity of accurate measurement between the pipe endand thelitting to which `the pipe is to be connected which is usuallyset in a ce== ment icor 'tor instance, the.- thiclrness of which varies.under the various conditions and in which the member 1 is to be set asindicated by dotted lines 11 in Fig.` l; By

lcaulking the ferrule end to the member 1, as indicated at 12,possibility of leakage be.-` Vtween the ferrule and the member 1 isavoided.

From the foregoing description it is evi- A ferrule for connecting aplumbing fittingV Ywith a pipe comprising ahollow tubular member open atone end and externally threaded at the said end for introduction in-`exterior of the; Wall `portion of a form to providea wrench hold,thewall of the errnle nbrw the Wrench l to the pipe, a portion ofthewall of the feri rule abovethe threaded bengof greater thickness thanthe remainin portion thereof, a shoulder'portion provi ed on the holdbeing formed With spaced circumferi at the said thickerl ential groovesproviding weakened lines .y along any one of which said ferrule may besevered, the opposteend of the fel-rule being closed by a wall integraltherewith, a central projecting boss at said closed end having athreaded aperture toreceive a plug for closing the same.
